We study quantum-impurity models as a platform for quantum thermometry. A single
quantum spin-1 2 impurity is coupled to an explicit, structured, fermionic thermal sample …

A tunable double optomechanically induced transparency (OMIT) with a squeezed field is
investigated in a system consisting of an optomechanical cavity coupled to a charged …

Quantum probes, such as single-and two-qubit probes, can accurately measure the
temperature of a bosonic bath. The current investigation assesses the precision of the …

Quantum probing consists of suitably exploiting a simple, small, and controllable quantum
system to characterize a larger and more complex system. Here, we address the estimation …

Quantum probing is the art of exploiting simple quantum systems interacting with a complex
environment to extract precise information about some environmental parameters, eg the …

We address a particular instance where open quantum systems may be used as quantum
probes for an emergent property of a complex system, as the temperature of a thermal bath …

Active optical media leading to interaction Hamiltonians of the form H= λ˜(a+ a†) ζ represent
a crucial resource for quantum optical technology. In this paper, we address the …

We explore the ability of a qubit probe to characterize unknown parameters of its

We address parameter estimation for structured environments and suggest an effective
estimation scheme based on continuous-variables quantum probes. In particular, we …

We address the use of a single qubit as a quantum probe to characterize the properties of
classical noise. In particular, we focus on the characterization of classical noise arising from …
